[llvm-commits] CVS: llvm/include/llvm/PassManagers.h

[Devang Patel]

Changes in directory llvm/include/llvm:

PassManagers.h updated: 1.5 -> 1.6
---
Log message:

- Undo previous check-in (i.e. Do not export TimingInfo class through
PassManagers.h).

- Add StopPassTimer() and StartPassTimer() to expose TimingInfo to
CallGraphPassManager

- Use these two APIs in CalLgraphPassManager to measure timings.
